Answer:
a= 2 b=-1
Step-by-step explanation:
a-3b=5
or, a= 5+3b_(i)
substituting value of a in 2a+b=3,
2×(5+3b)+b=3
or, 10+6b+b=3
or, 7b=3-10
or, 7b=-7
b= -1
substituting value of b in(i),
a=5+3b
=5+3×(-1)
=5-3
=2

Hint: Think of the equation for average
A) L+ m
B) Lm
C) L-m
D) L/m
E) m-L
Answer:
Lm
Step-by-step explanation:
average = (sum of numbers)/(number of numbers)
Solve the equation for "sum of numbers":
sum of numbers = average * number of numbers
sum of numbers = m * L
sum of numbers = Lm
Answer: B) Lm

What is the midpoint between (3, -1) and (7, -5)?
Group of answer choices
Answer:
The answer is
( 5 , - 3)Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(3, -1) and (7, -5)
The midpoint is
[tex]M = ( \frac{3 + 7}{2} , \: \frac{ - 1 - 5}{2} ) \\ = ( \frac{10}{2} \: , \: - \frac{6}{2} )[/tex]
We have the final answer as

A mixture of green paint contains 10 cups of blue paint and 15 cups of yellow paint. To make the same shade of green paint using 90 cups of blue paint, how many cups of yellow paint would you need?
Answer:
135 cups of yellow paint
Step-by-step explanation:
I made a table and the way i did that was
i made two columns one titled blue and the other yellow
then i plugged the numbers in 10 over 15 then 90 over x
i then did 10 times 9 to get 90
so the final step was to multipy 15 by 9 to get 135

# - A circle has an area of approximately
201.06 cm². If the radius is doubled, what is the
approximate area of the new circle? Show your
work below.
Answer:
The area of the new circle is 804.57 cm^2
Step-by-step explanation:
In this question, we are interested in calculating the area of the new circle of the radius of the old circle was doubled.
Let’s calculate the former radius first;
Mathematically;
Area of a circle = π * r^2
Thus;
201.06 = π * r^2
r^2 = 201.06/π
r^2 = 63.999
r = √63.99
r = 8 approximately
Now let’s double this radius and it becomes 2 * 8 = 16 cm
The new area will be ;
22/7 * 16 * 16 = 804.57 cm^2

Given g(x) = -x - 5, find g(1).
Answer:
-6
Step-by-step explanation:
g(1) would be equal to g(1) = -(1) - 5 = -6
So, the answer would be -6.
The value of g(1) is -6.
Given,
g(x) = -x - 5
We need to find g(1).
What is the domain and range of a function?A function is given by f(x).
The value of x is called the domain.
The output we get after putting the domain x in the function is called the range.
Example:
f(x) = x + 2
x = 1
f(1) = 1 + 2 = 3
domain = 1
range = 3
Find g(x) at x = 1.
g(x) = -x - 5
Put x = 1
g(1) = -1 - 5
= -6
g(1) = -6 is our answer.
Thus the value of g(1) is -6.

What is the mean absolute deviation? Round to the nearest tenth.
Answer:
The mean absolute value is 7.7, when rounded to the nearest tenth.
Step-by-step explanation:
1.) To get the mean absolute deviation you have to find the mean first:
32 + 35 + 20 + 16 + 28 + 13 = 144 ÷ 6 = 242.) Then, you have to find the difference of each element in your data set that is away from the mean. Then, you have to find the absolute values of the answers:
32 - 24 = | 8 | → 835 - 24 = | 11 | → 1120 - 24 = | -4 | → 416 - 24 = | -8 | → 828 - 24 = | 4 | → 413 - 24 = | -11 | → 113.) Then, you have to find the mean of the absolute values:
8 + 11 + 4 + 8 + 4 + 11 = 46 ÷ 6 = 7.6666666666666666666666666666667 = 7.7Answer:
